Description

[Detailed description of the invention] <Industrial field of application> This invention relates to the structure of a packaging case that repeatedly houses radio cassettes and other electrical appliances.

<Prior art> As shown in FIGS. 4 and 5, a conventional packaging case has inner flaps 3, 3, which are arranged facing each other on the ridge lines of side panels ₁₁ , _12, respectively, bent inward, and Each tongue piece 1 is formed on the outer flaps ₉ , 9 by folding the outer flaps 9, 9, which are continuous on the ridge lines of the face plates 71, ₇₂ , over the inner flaps 3, 3.
1, 11 are the wide parts 4, 4 of the inner flaps 3, 3.
After inserting the case into the slits 6 and 6 provided in the slits 6 and 6 to form an assembled unit packaging case as shown in FIG. (see Figure 5).

<Problems to be Solved by the Invention> However, in the above conventional example, when inserting the unit packaging case into the exterior body 14, the tongues 11, 11 of the outer flap 9 are inserted into the slits 6 of the inner flap 3. Therefore, there is no problem when inserting the unit packaging case into the exterior body 14.
The tongue piece 10a works to suppress the narrow part of the inner flap 3, but since the tongue piece 10a protrudes outward by the thickness of the material, when the packaging case is inserted into the outer case 14, the tongue piece 10a is pressed against the end face 14'. Because it collides and prevents insertion,
In order to insert the tongue piece 10a, it was necessary to slide it in the direction of the arrow while particularly holding down the tongue piece 10a and inserting it into the exterior body.

Therefore, the present invention provides a packaging case that allows such unit packaging cases to be easily stored in the exterior body without requiring any special consideration.

<Means for solving the problem> The box consists of an inner flap and an outer flap provided on the ridge lines of the four side panels forming the box, and the inner flap is provided with a slit and a recess, and the outer flap is provided with a slit and a recess. A square tongue piece and a trapezoid tongue piece are arranged side by side on the outer ends, each side plate is assembled into a box shape, each flap is bent, and when the square tongue piece is inserted into the slit, the top edge of the other trapezoid tongue piece is The flap contacts the recess to eliminate the difference in thickness between the inner flap and the outer flap.

<Function> When each side plate is assembled into a box shape, the inner flap and outer flap are folded over, and the rectangular tongue piece formed on the outer flap is inserted into the slit on the inner flap, the top edge of the trapezoidal tongue piece is recessed into the recess on the inner flap, and a part of the trapezoidal tongue and the inner flap form the same plane. This and the trapezoidal hypotenuse of the trapezoidal tongue make it possible to create a packaging case with the above structure. When inserting into the exterior body, the effect of the difference in level is absorbed and it can be inserted easily.

<Example> Hereinafter, the present invention will be described in detail with reference to an example shown in the drawings.As shown in _FIG .
₁ , 1 ₂ , and 7 ₂ are successively arranged in series, and the side plates 1 ₁ ,
Inner flaps ₃ , 3 are formed on the circumferential ridge lines 2 ₁ , 2 ₂ of the flap 1 2, and a wide portion 4 is provided in the inner flap 3, and a slit 6 is formed extending in a direction perpendicular to the ridge lines 2 ₁ , 2 ₂ . Furthermore, a cut recess 5 is provided at the edge of the wide portion 4.

Further, outer flaps 9, 9 are provided in succession on the ridge lines 8 ₁ , 8 ₂ of the side plates 7 ₁ , 7 ₂ , and the outer flaps 9, 9
A square tongue piece 11 and a trapezoidal tongue piece 10 having an oblique side 12 are arranged side by side at the end of each side plate 1 ₁ ,
7 ₁ , 1 ₂ , and 7 ₂ are sequentially bent and a connecting piece 13 protruding from one end is attached to the side of the side plate 7 ₂ to form a frame edge shape as shown in FIG. 3.

Then, the inner flaps 3, 3 are bent to butt each other, and the outer flaps 9, 9 are bent.
Similarly to the flaps 3 and 3 above, turn the third flap inwards.
As shown in FIG.
a slit 6 provided in the wide part 4 of the inner flap;
Insert from the tip inside. As a result, the outer flap 9
The trapezoidal tongue piece 10 suppresses floating of one inner flap 3 while its top side abuts and engages in the notch recess 5.

A plurality of packaging cases assembled in this manner are simultaneously inserted into the exterior body 14 as shown in FIG.

In assembling the above-mentioned packaging case, the bottom part may be formed by folding the four bottom plate pieces one on top of the other in sequence, as is usually done, or by folding the opposing pieces symmetrically and using adhesive tape at the seams. The bottom part may also be formed by attaching it to the base.

By having the present invention configured as described above, the square tongue pieces 11, 11 of the outer flap 9 are connected to the slits 6,
At the same time, the square tongue pieces 11, 1
1, the top side of the trapezoidal tongue piece 10 formed adjacent to the trapezoidal tongue piece 10 recesses into the notch recess provided on the inner flap, and the part in contact with the recess has both sides due to the thickness of the material. By making the edge portion of the trapezoidal tongue not in contact with the recess 5 an inclined side 12 toward the base of the outer flap, the exterior body 1
When inserted into the trapezoidal tongue 10, the distal end surface 14' of the outer body 14 smoothly moves from the outer surface of the inner flap onto the top of the trapezoidal tongue 10 at the part of the recess 5 with no step, and also Since the joining point with the end surface 14' moves relatively due to the inclination of the inclined side 12, the tongue piece 10 and the end surface 14' of the exterior body no longer face each other, and can be easily inserted without causing a collision. It is possible.

<Effects of the invention> Since the present invention is constructed as described above, when a plurality of unit packaging cases are lined up and inserted into the exterior body, the tip of the tongue of the packaging case does not meet the tip of the exterior body as in the past. There is no collision and the insertion is easy.

In addition, as mentioned above, since there is no collision between the two, there is no damage to the packaging case even after repeated use, making it suitable for repeated use over a long period of time, making it a highly practical idea with excellent effects.
